Observation consists of receiving knowledge of the outside world through our senses,or recording information using scientific tools and instruments.Any data recorded during an experiment can be called and observation.
Sameee! I just wake up and I already wanna go take a nap lol
The percentage yield of the product if the actual yield was measured as 2.80 g and the theoretical yield is measured as 3.12 g is 11.43%.
<h3>How to calculate percentage yield?</h3>
The percentage yield of a substance can be calculated by dividing the difference between the actual and theoretical yield by the actual yield, then multiplied by 100.
Percentage yield = (theoretical yield - actual yield)/actual yield × 100
According to this question, the actual yield of a product in a reaction was measured as 2.80 and the theoretical yield of the product for the reaction is 3.12 g.
Percent yield = (3.12g - 2.80g)/2.80 × 100
Percent yield = 11.43%.
Therefore, percentage yield of the product if the actual yield was measured as 2.80 g and the theoretical yield is measured as 3.12 g is 11.43%.

Answer:
c = λ x ν
v =c/λ=(3*10e8)/(5.00 x 10e-5)=6000000000000
f = v/λ =6000000000000/5.00 x 10e-5=120000000
Explanation:
Answer:
Force=mass ×acceleration.
20=10×acceleration.
20=10a.
a=2m/s^2.
